 #### Implementation Checklist
 
-- [ ] Remove `persist_provisioning_state()` from `ProvisionCommand`
-- [ ] Remove `persist_provisioned_state()` from `ProvisionCommand`
-- [ ] Remove `persist_provision_failed_state()` from `ProvisionCommand`
-- [ ] Remove `persist_configuring_state()` from `ConfigureCommand`
-- [ ] Remove `persist_configured_state()` from `ConfigureCommand`
-- [ ] Remove `persist_configure_failed_state()` from `ConfigureCommand`
-- [ ] Replace all method calls with direct `self.repository.save(&env.clone().into_any())?`
-- [ ] Update repository implementation to log errors at ERROR level
-- [ ] Add error context to repository errors (which state, which file, etc.)
-- [ ] Update command error types to include `RepositoryError` if needed
-- [ ] Verify tests still pass (or update tests expecting different error behavior)
-- [ ] Run linter and fix any issues
-
-#### Testing Strategy
-
-- Existing tests should mostly continue to work
-- Tests expecting commands to continue on persistence errors will need updates
-- Add tests for commands failing when repository returns error
-- Verify repository error messages include proper context
